FORD PATS (PASSIVE ANTI THEFT SYSTEM)
INITIALIZATION WITH THE
There are five types of PATS implementations from Ford (A, B, C, D, E). Refer to Table 1 (page 11) to
identify what type of PATS your vehicle is equipped with. PATS initialization is generally performed after
programming.
The A or D version of PATS does not store the key information in the PCM, therefore NO PATS KEY
RELEARN IS REQUIRED after programming.
The B or C versions of PATS store the key information within the PCM and MUST be transferred to the new
PCM, or relearned on the vehicle after the new PCM is installed.
The E version of PATS also stores the key information within the PCM, but CANNOT be transferred to the
new PCM. This type MUST be relearned on the vehicle after the new PCM is installed.
Note: If you are just updating the existing PCM calibration with an update calibration, you must
select the MODULE REPROGRAMMING function (not Programmable Module Installation).
Doing this will insure you retain the existing PATS key information.
IF REPROGRAMMING AN UPDATED CALIBRATION TO AN EXISTING
PCM (ALL PATS TYPES)
The Module Reprogramming selection MUST be selected, not reprogram and install (this will avoid a key
relearn procedure).
If REPLACING OR INSTALLING A NEW PCM (B, C TYPES ONLY)
The Programmable Module Installation selection MUST be selected. To transfer your PATS key information
to the new PCM, your original PCM must be connected to the global programmer first. This must be done
to avoid a key relearning procedure. If the original is unavailable, a PATS key relearn procedure must be
performed after the PCM is installed on the vehicle.
PATS KEY RELEARN (B, C TYPES)
A key relearn procedure for PCMs containing B or C type PATS systems is completed by performing a
PARAMETER RESET function. This function must be performed ON THE VEHICLE and cannot be
performed off board. This function is performed by using a scan tool with PATS capability or via the FORD
website using the PATS feature.
The FORD website feature is detailed below. The scan tool feature will be similar. Please refer to your scan
tool operation manual for instructions.
Select PATS Functions from the Module Programming screen.
The boxes in red indicate the vehicle contains the B or C implementation of PATS:
In some cases the PATS Control Function Location may have another entry other than PATS, for example:
ICM, IC, HEC, EC, etc. If this lists PCM, then it is a PATS type E system. Refer to the PATS E type key
relearn procedure in the following section.
There is a mandatory 10 minute security access delay. Please wait 10 minutes.
Select PARAMETER RESET.
Select YES to continue.
The Parameter Reset will be performed. This function only takes a few seconds.
Select PCM and follow the instructions to start the vehicle.
PATS KEY RELEARN (E TYPE)
!IMPORTANT! Two keys will be needed to start the vehicle. If two keys are not available, you will
not be able to start the vehicle.
There is a mandatory 10 minute security access delay. Please wait 10 minutes.
A Security Access confirmation screen will appear. Click on the check mark to continue.
Select Ignition Key Code Erase.
!IMPORTANT! Two keys will be needed to start the vehicle. If two keys are not available, you will not be
The Ignition Key Code Erase function will be performed. This function only takes a few seconds.
Click the check mark once the Ignition Key Code Erase function is completed successfully.

PATS DTC CHART
DTC DESCRIPTION
B1213 Less than 2 (or 3 if equipped w/Valet key) keys programmed to the system.
B1232/B2103 Transceiver internal antenna damaged. Replace transceiver.
B1342 ECU is defective (EEPROM in PCM is not working- replace PCM). PATS related when stored in PCM only.
B1600 Non-PATS key or damaged key.
B1601 Unprogrammed encoded ignition key detected (leave ignition on for 20 seconds before trying a programmed
key, in Anti-Scan Mode).
B1602 Partial detection of encoded ignition key.
B1681 Transceiver signal not detected.
B2141 Non-Volatile Memory (NVM) configuration failure - No PCM ID stored in PATS.
B2139 PCM ID does not match between the PCM and PATS control (PATS/ICM/VIC/HEC/SCIL).
B2431 Key programmed failure (defective key or transceiver)
U1147/U1262 Communications issue, SCP (J1850), between PCM and PATS control (PATS/ICM/VIC/HES/SCIL).
P1260 PCM disabled the vehicle because of a PATS concern. Retrieve DTC’S from applicable PATS control function
(PATS/ICM/VIC/HES/SCIL).
It is not a PATS Issue, if:
• The “Service Engine Soon” light is illuminated. (Investigate PCM system)
• There is no communications with PCM ; PCM will always communicate on the diagnostic link regardless of theft status.
(Investigate PCM system)
• Engine stalls on road: Once the engine runs for one second, PATS CANNOT disable the engine. Running stalls are not
PATS issues.
• Alarm goes off: PATS is completely separate from the perimeter alarm system (if installed). PATS will not cause the
alarm to go off.
• Remote Entry/Keyless Entry problems: PATS is completely separate from the Remote Entry/Keyless Entry systems.
• There is a no-crank problem on vehicles without PATS starter disable. Check Table 1, for presence of Starter Interrupt.
• PATS Theft Indicator flashes every 2 seconds at Ignition OFF. This is normal operation for PATS to act as a visual theft
deterrent. (See chart on reverse side for applicable system.)
• PATS Theft Indicator stays on for 2 or 3 seconds (depending on system type) at Ignition RUN or START and then off.
This is normal operation for PATS proveout.
Basics
• Erasing and reprogramming ignition keys does not cure any known intermittent PATS no-start issues. Do not reprogram keys if
a fault cannot be identified.
• Always verify that there are no aftermarket devices causing interference, such as alarms, remote starters or other devices
utilizing transponders. Devices that power up the PCM without powering up the PATS Control module can experience no-start concerns.
• Items such as foil stickers, brass key tags, other PATS keys, and other transponders used to purchase gasoline or other metallic
objects can cause interference with the PATS key.
• Make sure you have all of the customer’s keys when doing reprogramming, PATS Control module replacing, or diagnosis.
• When replacing ignition keys, make sure the customer throws out all old keys or programs them as spare keys.
• Reprogramming the PCM does not have any impact on PATS operation.
• Disconnect battery cables when replacing the PATS modules, (ICM, VIC, HEC, SCIL, or PCM)
• If the engine does not crank on vehicles that have PATS providing a ground to the starter relay, verify the PATS output to the
starter relay.
• If the PCM has a P1260, look for additional codes in the PATS control module.
• Systems B, C and E have an anti-scan function. If you attempt to start the vehicle with an unprogrammed key, the theft indicator
will flash rapidly and the vehicle will not start. Leave the key in the RUN position for 30 seconds for the anti-scan feature to time out. The vehicle will fail to start during this 30-second time period even if a correctly programmed key is used.
• Some aftermarket audio equipment have been found to keep the run/start circuit active for over 5 seconds past ignition off. This
can prevent pats from properly reading ignition keys during key programming. Remove or disable this aftermarket equipment if problems with any key programming sequence occur.
